# STACK B — NON-DEPLOYMENT CLOSURE REPORT

Version: `0.1.0-STACK-B-NON-DEPLOYMENT-CLOSURE`  
Date: `2026-08-23`  
Status: `CANDIDATE STATIC CLOSURE / NON_RUNTIME / NO_AUTHORITY_EFFECT`

## 1. Scope

This report closes the tests that remain inside `M2M-STACK-B-01` after the low-token benchmark moved to `M2M-DEPLOY-03` in Backlog. It tests candidate interfaces and decision laws; it does not execute an upstream OPERA or claim runtime deployment evidence.

## 2. Contextual interface fixtures

The closure corpus provides 15 deterministic cases covering:

- a software-domain portability case with an explicit weaker relation;
- a formal full-support categorical interface case;
- missing A, S/K, T, and RQ providers;
- complete and carrier-corrupted RQ ancestry;
- independent S1, A, R, T, and S2 carrier swaps when combined with the existing adverse fixture;
- ambiguous, contradictory, deliberately lossy, and overpredicating inputs.

Every contextual case is labeled as a synthetic interface fixture. Provider IDs and source contracts are trace fields, not claims that the candidate executed those OPERAE.

## 3. Deterministic decision order

```text
carrier drift                         -> REJECTED / CARRIER_MISALIGNMENT
contradictory predicative evidence    -> REJECTED / PREDICATIVE_CONTRADICTION
incomplete RQ ancestry                -> REJECTED / RQ_ANCESTRY_INCOMPLETE
missing A, S/K, or T provider         -> SUSPENDED / UPSTREAM_OPERATUM_MISSING
ambiguous or insufficient support     -> SUSPENDED
explicit weaker support               -> CONTRACTED
full support and perfect alignment    -> CATEGORICAL
```

A request for categorical language over explicit weaker support is reduced to `CONTRACTED` and records `OVERPREDICATION_DENIED`.

## 4. Proportional-pair result

The E→K and B→C fixtures preserve the same source/target carrier relation across A, T, R, and S projections. This is a structural test result only. Whether the projected meanings instantiate a stronger morphism-like semantic law remains `HYPOTHESIS_UNRESOLVED`.

No causal or ontological claim about numerical carrier quality is made here.

## 5. Canonical-to-applied reflection result

The fixture admits only a `REFLECTION_CANDIDATE` when canonical medium evidence exists, carriers are preserved, the contraction is valid, and subject/species admission is present. Corrupted carrier rejects; bad contraction and insufficient admission suspend.

This validates failure discipline without proving that every canonical medium naturally reflects into every application.

## 6. Stack G and virtue boundaries

The closure corpus retains Stack G's heterogeneous invariant of 12 statements, 12 media, and 24 questions, with `stack_b_executes=false`. It also keeps `A_H = Virtus` distinct from derived A×T virtue/vice results, generates none of those results, and does not simulate the separate stack.

## 7. Validation outcome

The extended deterministic validator reports:

```text
STACK B VALIDATION: 39 passed; 0 failed
```

The low-token 24-run benchmark is not included in this count and is not required for this slice's closure.

## 8. Remaining authority gate

The candidate is statically complete for the present non-deployment development scope. Integration, SYSTEM_INDEX registration, runtime execution, Sigma generation, and deployment remain separate human decisions. The unresolved semantic hypotheses are preserved as hypotheses rather than promoted through test mechanics.
